Emerging Ethical and Legal Dimensions of Patenting 3D Bioprinting Biomaterial Based Technologies for Equitable Access to Medicines

Abstract

The emergence of advanced biomaterials and bioink-based 3D bioprinting is revolutionizing drug discovery and drug delivery by enabling the fabrication of complex biological structures. However, the patentability of such technologies introduces ethical and legal challenges, particularly concerning access, affordability, and innovation. This study examines the evolving patent landscape of biopolymer-based bioinks and highlights how ethical and legal considerations influence the trajectory of 3D bioprinting technologies. A patent portfolio analysis was conducted to assess the inventiveness, translational potential, and commercial viability of bioink applications in biomedical research. The findings provide critical insights into how intellectual property frameworks can either facilitate or hinder the development of affordable and accessible medicines, an essential component of the universal right to health. The study further argues for tailored regulatory and R&D strategies that account for the multifaceted legal complexities associated with 3D bioprinting and bioink based innovation.
